TO ALL WHOM IT MAY CONCERN:

Be it known that I, ANDREW HARTMAN, of Canton, in the county of Stark, and State of Ohio, have invented new and useful improvements in Car-Couplings; and I-do hereby declare that the following is a full, clear, and exa'ct description of my invention, reference being had to the accompanying drawings, forming a part of this specification,`and to the letters of reference marked thereon, in which drawings- Fig'ure 1 is a sectional view of my improved car-coupling.

Figure 2 is a plan ofthe same; and

Figure 3 is an end view of the same.

The nature of my invention consists in the novel combination of a swinging-pin, sliding-block, and spring and catch, with the box of a coupling, so as to form a self-operating coupling; also in so constructing the swingingpin as that when turned back its lower part shall form withthe front of the box' ot`A the coupling a complete funnel-shaped mouth.

To enable others skilled in the art tomake and use my invention, I will proceed to describe its construction and operation.

'The coupling-box is made ofthe part A, bent in form shown in g. 2, and the part B, which has the bolts b passing through the part A, thus firmly connecting them. The parts A. and B are made of iron or steel, and the bolts b pass through suitablyformed staples in the part B, as shown in iig. 1. The catch is made as shown, the axes apassing through the two sides of the partA, and the piece G projecting down through the hole d in the part B. `The pin E Z D is of peculiar form,l being composed of the pin proper E, -the axial parbZ, and the counterpoise or'balance D, the whole forming a rotating pin rotating around the axis or bolt H, which passes `through the two sides of the part A andthe `rotating pin E Z D, as shown. The Vblock J has the pins O Olin its sides, which pins pass through the slotted 4holes S S and project through the two sides of the part `A of thc coupling-box, thus supporting vthe block J and giving a means of sliding it from the outside of the coupling-box. The block J has the rod K at its rear end, which rod passes through the' iron z, and has the spiral spring L around it and between the block J-and iron :c which keeps the block J pressed forward. In figs. 1, 2, and 3, the link F is shown as it appears when drawing the car. By raising the catch C by means of the handle I, which can be easily reached from the platform ofthe car, or by having a rod or cord attached, can be operated from the top of the car, the rotating pin E Z Dfftakes the position E2 Z D2 and allows the link F to slip ofi' over the end of the pin E, thus uncoupling the cars. When the link F is put in the position shown, by rotating the pin E Z D in the position :E1 Z DI, the end of the pin E first forcing back the block J, which, as soon as said pin E passes the part T of the block, by the 'action of the spring L assumes its original position, thus scouring tho rotating pin in the positonEl Z D1, which holds the link in position F as shown. The lip V on the block J qzrevents the rotating pin from turning too far and getting under thc block J. The link being held in position AE, inthe coupling, and coming to a coupling with rotating pin in position E, Z D1, causes said pin to rotate till the end of" the pin E strikcsthe block J, the end of the .link then sliding up on the piu E till it comes to the part T of the block J, when it causes said block to slide back, thus releasing the rotating pin, which assumesu its original position, the pin E coming up into the link F, and the coupling ofthe cars is thus ei'ected. When the swinging-pin is held by the block J in the position El Z D1, it is readily seen that`the part D forms with the pieces A. and B a' funnel-shaped mouth, so that a link coming in any direction, whereby it would enter the mouth of the coupling, would be guided by the sides of this funnel-shaped mouth up over the pin El andvagainst the block J, und the coupling would be effected, as before shown. v

Having thus fully describedmy invention, what I claim/as new, and desire to secure by Letters Patent, is-

l. The peculiarly-shaped apron or balance D of the pin E Z D, -so arranged and constructed as to act both as a balance and a part of. the mouth of the coupling, substantially in the manner and for the purpose herein specified. I 1

2. The peculiar combination and arrangement of the parts A and B, rotating pin E Z D, bolt H, block J, spring L, iron K, Apins O 0, slots S S, catch C with handle I, the several parts being arranged as hereinbefore shown, and-the whole forming a self-acting coupling, operating substantially in the manner specified.

As evidence that I claim the foregoing I have hereuntosct my hand in presence of two witnesses.
